T0 all whom it may concern;

Be it known that I, CULLEN L. LYTTON, a citizen of the United States of America, and a resident of Gastonia, county of Gaston, and State of North Carolina, have invented certain new and useful Improvements in Tools for Attaching Paper Tubes to Winders, of which the following is a full and clear specification.

In winding yarn upon paper cop tubes, the tubes are fastened to stationary pins supported in the winding-machine. These tubes fit the pins snugly; in order to anchor them against turning on the pins as Well as against slipping off the pins, the pins are provided at their inner ends with a few screw-threads and the tubes are screwed thereon, the threads on the pins cutting or forming threads in the comparatively soft paper by the mere act of screwing the tubes home. These tubes have heretofore been applied to the carrier-pins by hand, and this operation has been not only painful but also slow and laborious by reason of the tight fit of the tubes and the necessity for forcibly screwing them home. It is the object of the presentinvention to provide a simple tool for putting the tubes in place on the pins.

In the drawing- Figure 1 is a side elevation of my tool;

Fig. 2 is a vertical longitudinal sectional view taken through the grippersocket;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. l is a side elevation of a part of the mechanism of a tube-winding machine showing the manner in which the tube is anchored thereto. D

Referring to Fig. 4 of the accompanying drawing, 1 have illustrated a fragment of a well-known winding machine, the usual holding-pin being shown at a and the paper tube being shown at b. The tube fits the pin tightly and is secured against loosening dur ing the winding operation by the screwthreads 0 formed at the base of the pin. Ordinarily in applying this tube to the pin, it is forced down over the pin by hand and then given a few turns to screw it home. This operation is not only slow but 18 also painful to the hands of the operatives who do this work.

The preferred form of my tool is shown in the figures of the drawing. I prefer to employ a brace-and-bit type of tool, as shown in Fig. 1, which consists, as usual, of a pressure-knob Z, a crank e and a socket f. This socket consists of an exteriorly fluted frusto cone 9 and a cap it spaced away from the cone sufiiciently to form an annular chamber for the reception of the outer end of the paper tube. The diameter of this annular space is slightly less than the diameter of the tube, so that when the end is inserted and forcibly pressed into the annular space the longitudinal flutes on the cone will be embedded in the interior wall of the tube, as shown in Figs. 2 and 3. The interior of the cap or ring it fits the tube closely, so as to prevent the tube being ruptured by spreading when it is jammed into the socket. The conical shape of the fluted gripping device 9 together with the beveled outer edge 2' of the ring it facilitates the insertion of the tube into the socket, as is obvious. WVhen the paper tube is thus jammed into the socket, it is of course held rigidly against rotation therein, so that the paper-tube may be readily applied to the carrier-pin a by simply sliding it down on the pin and then giving the tube a few turns by means of the braceandbit crank.

The conical gripping-device g is in the form of a tube which is rigidly affixed to the end of the crank-shaft, and this tube is enlarged at its inner end to form a headj which fits the interior of the cap it and is rigidly afiixed thereto, but it will be understood that the details of construction may be varied considerably without departing from the spirit of the invention as defined in the claims.

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is:

1. In a tool of the class described, a socket and an implement for rotating the socket, said socket having means for gripping by crushing action the end of a paper cop tube at points around its outer as well as its inner side.

2. In a tool of the class described, a socket and an implement for rotating the socket, said socket having means for gripping the end of a paper cop tube, said means consisting of inner and outer members forming an annular chamber tapering inwardly so as to grip the tube around its outer as well as its inner face when the tube is jammed thereinto.

3. In a tool of the class described, a socket and an implement for rotating the socket,

said socket having means for gripping the end of a paper cop tube, said means consisting of an outer cylindrical member and an inner conical member rtapering outwardly adapted to grip the tube When the tube is jammed in between said members.

4:. In a tool of the class described, a socket and an implement for rotatingthe socket, said socket having means for gripping the end of apaper cop tube around its-outer as Well asitsinner side, said means consisting of inner and outer-members forming. anannular chamber tapering inwardly one or which is flutecbto form gripping-members, substantially asset forth. 7

5. In a tool of the class described, a socket and an implement for rotating the socket,

said socket having means for gripping the end oi a; paper cop tube, SitlCllfiEEtIlS consisting of an inner fluted conical member and an CULLEN 1L. LYTTON.
